Application filed February 28, 1905. Serial No. 247,7/ i' T 0 1f/ZZw/tom/ it T11/(ty concern:

Be it known that we, PHILIP VooRHnEs and HENRY JOHN TRAH, citizens ofthe United States, and residents of Logansport, in the county of Cassand State of Indiana, have invented a new and Improved Controlling-Valve, of which the following is a full, clear, and exact description.

Our invention relates to valves for controlling the flow through variousconduits, it being particularly applicable to the rain-water conductorsof buildings. Its principal object is to provide means for directing towaste the first flow through the conductorv at the beginning of arainfall, this being liable to be fouled by dirt accumulated upon theroof and in the glitters, and then automatically delivering a succeedingflow to the cistern or other container which is to receive it.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a broken side elevation of one embodiment of our invention.Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is acentral transverse section through the cut-off or valve proper. Fig. 4is a longitudinal section therethrough on the line 4 4 of Fig. 3, andFig. 5 is a horizontal section taken above the lip of thecontrolling-conduit and showing another form of our invention.

A main conductor or conduit 10 is shown as terminating in branchconduits 11 and 12, which are to receive the waste and clean water,respectively. Mounted at the juncture of the conduits is a cut-off orvalve 13, which is preferably generally trough-shaped and is so situatedthat when in one extreme position (that shown in full lines in Fig. 1 ofthe drawings) it directs the flow from the main conduit into thewaste-conduit, while when in its opposite position(as is shown in dottedlines) it directs the discharge to the cleanwater conduit. The valve maybe laterally reinforced at its center by adjacent double folds 14 14,formed by bending the material from which the valve is constructed, thisbeing preferably sheet metal, first inwardlynntil it meets at the centerand then outwardly, the folds lying in contact with one another.

The valve may be supported at one side by aA stud 15, which projectsthrough the wall of the intersection of the conduits into an opening 16at one side of the valve, while from the opposite side an arm 17,conveniently formed of Wire, first extends through two openings 18 18,which serve to fix the arm in place, then outwardly at 19 through anopening in the conduit-wall, and finally downwardly at 20, substantiallyparallel to the waste-conduit, to furnish a lever-arm weighted at itslower end 21. Connected to the arm 17 is an arm 22, extending upon theopposite side of the fulcrum of the lever, first encircling the portion20 of the first-named arm at 23, then extending along the arm and beingagain bent to surround the portion 19 at 24, and finally projectingupwardly, where it terminates in an eye 25, the function of which willbe hereinafter stated. Extending into the interior of the main conduitfrom one side is a lip 26, having an inclined upper edge at 27, which isshown as covered by a screen 2S. From the lower portion of this lipthrough the conduit opens a controlling-conduit 29, which projectsdownwardly substantially parallel to the main conduit, it lying within avessel or receiver 30, which is movably mounted upon guides 31, carriedby the main conduit, the connection between the receiver and guidesbeing by means of pairs of eyes 32, fixed at each side of the receiver.Through the bottom of the receiver is a contracted outflow-opening 33 ofconsiderably less area than that of the controlling-conduit, thisopening leading into a spout or pipe 34, having its extremity lyingwithin an elongated recess 35, which extends longitudinally of the mainconduit and opens into the intersection of the conduits above the valve.The recess may be protected at its opposite sides by flanges 36 36,which tend to prevent wind from blowing the flowing water out of therecess. Along the inner side of the receiver, extending from top tobottom, is a passage 37, into which an overflow-opening 38 leads from apoint near the top of the receiver. This overflow-opening, in connectionwith the opening 33,is sufficient to conduct the entire dischargethrough the controlling-pipe from the receiver into the recess 35, whichleads it into the conduits. The receiver is supported by a link 39,connecting an eye 40, fixed to its lower extremity, with the eye 25 uponthe lever-arm 22.

At times when there is no rainfall, and therefore no flow through themain conduit, the weight 21 is sufficient to hold the receiver in itsextreme upward position and the valve tilted to deliver to thewaste-conduit. Then at the beginning of a rain the first flow car- IIOrying the dirt from the roof will pass to the waste. A portion of itwill be caught by the lip and directed into the receiver, the screenarresting any large particles of dirt and its inclined position servingto keep its meshes freed by the wash. This diverted portion of the flowenters the receiver and passes through the opening 33 into the spout andalong the recess to the interior of the conduit, where it is directed bythe valve with the main portion of the water into the waste. As theopening 33 is too small to permit the discharge of the controllingportion of the water as rapidly as it is introduced, it accumulatesuntil it overbalances the weight and causes the receiver to descend, thespout traveling along the conduit-recess and the controlling-conduitbeing of such length that its discharge-opening remains within thereceiver in all positions thereof. This movement of the receiver throughthe lever swings the valve upon its pivots until it assumes the positionindicated by dotted lines in Fig. 1, when the entire quantity of waterentering the main conduit passes into the branch conduit 12, the time ofoperation of the receiver being adjusted for any particular installationto eilect this movement of the valve after the water has becomepractically clean.

In the form of our invention illustrated in Fig. 5 the general operationis the same; but in this case instead of returning the controlling flowfrom the receiver to the conduits it is allowed to run to waste throughthe controlling-opening 41 in the bottom of the receiver and by overiiowat the top. Another arrangement of support of the receiver upon thelever is also shown, the upper arm having alined eyes 42 42, connectedby an integral bail 43 and receiving oppositely-projecting trunnions 44.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination with a main conduit havingan elongated recess and a plurality of branch conduits, said recessopening into one of the conduits, of a valve associated with thejuncture of the conduits, a movable receiver connected with the valve,and a pipe extending from the receiver into the recess.

2. The combination with a main conduit having an elongated recess and aplurality of branch conduits, said recess opening into one of theconduits, of iianges at opposite sides of the recess, a valve associatedwith the juncture of the conduits, a movable receiver connected with thevalve, and a pipe extending Jfrom the receiver into the recess.

3. The combination with a main conduit having an elongated recess and aplurality of branch conduits, the said recess opening into one of theconduits, of a valve associated with the juncture of the conduits, aremovable receiver connected with the valve, a pipe eX- tending from thereceiver into the recess, a lip projecting forwardly from the wall ofthe main conduit, said main conduit having an opening in its wall withinthe lip, and a controlling-conduit leading from the opening to thereceiver.

4. The combination with a main conduit and a plurality of branchconduits, of a valve associated with the juncture of the conduits, amovable receiver connected with the valve, a lip projecting inwardlyfrom the wall of the main conduit and being provided with adownwardlyinclined edge, said main conduit having an opening in its wallwithin the lip, a screen supported upon the inclined edge of the lip,and a controlling-conduit leading from said opening to the receiver.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
